Como resolver está expressão de Matemática? 10pontos 5 estrelas?

Faça divisão 1120 por 360 vai dar 3 e sobra 40° já esta no 1° quadrante... Faça a divisão 610 por 360 vai dar 1 e sobra 250, 250 - 180 = 70, então tem as funções de 70° a menos do sinal então será com sinal de negativo "-". A expressão vai resultar em: sen40 - (-cos70) = sen40°+ cos70° mas sen40=cos50 então cos50 + cos70 p= 70 q= 50 (p-q)/2=20/2=10 Resposta: a) cos(10°) Espero ter ajudado!

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
